Before making the block, you have to form each wedge. That's done by sewing across the wider end of each cut wedge. I just fold mine in half length-wise, then stitch across the end, chain piecing to save time.
Here's what a chain of stitched pieces looks like.
And here's the back side of a finished wedge. Now you can see how that pointed end happens.
I use a wooden point turner to help get sharp points at the top of each wedge.
I need 300 wedges so there is a lot of chain piecing and pressing ahead. That's ok; it is a good workday evening sewing project because I can work on it for 20 or 30 minutes after dinner and make real progress by the end of the week.
Cindy at Hyacinth Quilt Designs posted a tutorial for the block as she made her quilt. You'll find it here.
